Spin Glass Behavior(自旋玻璃行为)研究综述
Spin Glass Behavior 自旋玻璃行为 - Magnetic curves reveal the superparamagnetic and spin-glass behavior of both kinds of nanoparticles. [1] Magnetic characterization gives anti-ferromagnetic and spin-glass behavior with Neel temperature of 43 K. [2] In the temperature-dependent measurements, the zero-field and field cooled data points of Zn2MnO4 diverged at 13 K, suggesting a spin-glass behavior. [3] It is also found that the switch from 2D to 3D Fe order coincides with the magnetic measurements, which reveal spin-glass behavior below x = 0. [4] Besides, the thermal-magnetization M(T) curves confirm that the amorphous Mn78Si13B9 and Mn68Fe10Si13B9 samples exhibit a characteristic spin-glass behavior. [5] A spin-glass behavior is predicted to emerge at 0. [6] The results presented in this study highlight the key findings that spin-glass behavior of LiFe5O8 is strongly size-dependent. [7] GdMnIn is reported to crystallize in the hexagonal MgNi2-type structure presenting a spin-glass behavior with no magnetic order attributed to the triangular spin frustration of magnetic ions. [8] Temperature dependence of dc magnetizations suggests the spin-glass behavior established in the La0. [9] The spin-glass behavior is correlated with the observed exchange bias and the magnetic field dependence of spin-glass freezing temperature. [10] 6, the system exhibits a distinct spin-glass behavior below a spin-freezing temperature. [11] 2$ member exhibits the very rare anisotropic spin-glass behavior with only the $c$-axis spin component freezing below ${T}_{\mathrm{g}}$. [12] Electron Spin Resonance (ESR) measurements are also carried out in the LCMO multifunctional nanoparticle systems, which suggests the occurrence of Jahn–Teller glass analogous to the spin-glass behavior. [13] Incommensurate magnetic ordering and spin-glass behaviors have also been observed. [14] This study presents a strategy for obtaining magnetic assemblies with spin-glass behavior and controllable anisotropy while shedding light on the magnetic interactions of low-dimensional assemblies. [15] The magnetization as a function of temperature, measured both under zero-field cooled and filed-cooled conditions show the evidence of ferromagnetism and spin-glass behavior. [16] 0, showed irreversible antiferromagnetism with dominant ferromagnetism and spin glass behavior. [17] The competing antiferromagnetic and ferromagnetic interactions among Cu2+, Mn4+, and Ir4+ ions give rise to spin glass behavior, which follows a conventional dynamical slowing down model. [18] Combining with the spin glass behavior below the metamagnetic transition temperature from ferromagnetism to antiferromagnetism, we ascribe THE to the emergence of noncollinear spin texture arising from the competitions among various exchange interactions in the antiferromagnetic state. [19] We report the coexistence of the Kondo effect and spin glass behavior in Fe-doped NbS2single crystals. [20] Powder neutron diffraction studies on DyBaCo4O7 cobaltite showed an orthorhombic Pbn21 symmetry and signature of short-range 120 degree magnetic correlations of kagome layer and a spin glass behavior below 65 K. [21] A simple theoretical model considering first-, second- and third-neighbor interactions yields a phase diagram that accounts for both spin glass behavior and different superstructures. [22] Existence of spin glass behavior and competing magnetic interactions in the 0. [23] This disorder may be the cause of the spin glass behavior that is particularly evident in the nickel analog, which exhibits a spin freezing transition at TF = 7 K. [24] Moreover, at low temperatures a spin glass behavior was observed. [25] Spin glass behavior of phase-separated (PS) manganite La0. [26] Moreover, at low temperatures a spin glass behavior was observed. [27] Ac susceptibility data recorded in the range 70 K–5 K ruled out the presence of spin glass behavior in NCTO. [28]磁曲线揭示了两种纳米粒子的超顺磁性和自旋玻璃行为。 [1] 磁性表征具有反铁磁和自旋玻璃行为，Neel 温度为 43 K。 [2] 在与温度相关的测量中，Zn2MnO4 的零场和场冷数据点在 13 K 处发散，表明存在自旋玻璃行为。 [3] 还发现从 2D 到 3D Fe 顺序的转换与磁性测量一致，这揭示了 x = 0 以下的自旋玻璃行为。 [4] 此外，热磁化 M(T) 曲线证实非晶 Mn78Si13B9 和 Mn68Fe10Si13B9 样品表现出特征的自旋玻璃行为。 [5] 预计在 0 时会出现自旋玻璃行为。 [6] 本研究中的结果突出了 LiFe5O8 的自旋玻璃行为与尺寸密切相关的关键发现。 [7] 据报道，GdMnIn 以六方 MgNi2 型结构结晶，呈现出自旋玻璃行为，由于磁性离子的三角形自旋受挫，没有磁序。 [8] 直流磁化的温度依赖性表明在 La0 中建立了自旋玻璃行为。 [9] 自旋玻璃行为与观察到的交换偏差和自旋玻璃冷冻温度的磁场依赖性相关。 [10] 如图 6 所示，该系统在旋转冷冻温度以下表现出明显的旋转玻璃行为。 [11] 2$ 成员表现出非常罕见的各向异性自旋玻璃行为，只有 $c$ 轴自旋分量冻结在 ${T}_{\mathrm{g}}$ 以下。 [12] 电子自旋共振 (ESR) 测量也在 LCMO 多功能纳米粒子系统中进行，这表明 Jahn-Teller 玻璃的出现类似于自旋玻璃行为。 [13] 还观察到了不相称的磁排序和自旋玻璃行为。 [14] 本研究提出了一种获得具有自旋玻璃行为和可控各向异性的磁性组件的策略，同时揭示了低维组件的磁性相互作用。 [15] 在零场冷却和场冷却条件下测量的作为温度函数的磁化强度显示了铁磁性和自旋玻璃行为的证据。 [16] 0，表现出不可逆的反铁磁性，具有主要的铁磁性和自旋玻璃行为。 [17] Cu2+、Mn4+ 和 Ir4+ 离子之间竞争的反铁磁和铁磁相互作用导致自旋玻璃行为，其遵循传统的动态减速模型。 [18] 结合从铁磁性到反铁磁性的超磁转变温度以下的自旋玻璃行为，我们将THE归因于反铁磁状态下各种交换相互作用之间的竞争引起的非共线自旋织构的出现。 [19] 我们报告了铁掺杂的 NbS2 单晶中近藤效应和自旋玻璃行为的共存。 [20] 对 DyBaCo4O7 钴矿的粉末中子衍射研究表明，kagome 层具有正交 Pbn21 对称性和短程 120 度磁相关特征以及低于 65 K 的自旋玻璃行为。 [21] 考虑第一、第二和第三邻域相互作用的简单理论模型产生了一个相图，该相图说明了自旋玻璃行为和不同的上层结构。 [22] 0 中存在自旋玻璃行为和竞争性磁相互作用。 [23] 这种无序可能是自旋玻璃行为的原因，这在镍类似物中特别明显，在 TF = 7 K 时表现出自旋冻结转变。 [24] 此外，在低温下观察到自旋玻璃行为。 [25] 相分离(PS)亚锰酸盐La<sub>0的自旋玻璃行为。 [26] 此外，在低温下观察到自旋玻璃行为。 [27] 记录在 70K-5K 范围内的交流磁化率数据排除了 NCTO 中自旋玻璃行为的存在。 [28]
Typical Spin Glass Behavior
Typical spin glass behavior is observed at low temperatures. [1] Furthermore, all the doped ceramics undergo a ferromagnetic to paramagnetic transition, and show typical spin glass behavior, which is confirmed by the isothermal remnant magnetization and Memory Effect. [2]在低温下观察到典型的自旋玻璃行为。 [1] 此外，所有掺杂的陶瓷都经历了铁磁到顺磁的转变，并表现出典型的自旋玻璃行为，这由等温剩磁和记忆效应证实。 [2]
