Abstract As-cast ingots of Mn100−xZx with Z = Al, Ge, Mn, Fe and Co all have the A13 βMn structure up to some maximum value of x. The magnetic susceptibility of pure βMn is ≈ 9 × 10−4 from 4 to 400 K, but the field-cooled and zero-field-cooled susceptibilities of all doped samples increase at low temperature and they bifurcate at a spin-freezing temperature Tf that increases with x, linearly at first. Point contact Andreev reflection shows evidence of a net spin polarization in a spin glass sample but not in the pure βMn spin liquid. Fixed-moment density functional calculations indicate a very shallow energy minimum (

具有立方 A13 (β-Mn) 结构的锰基合金中的自旋液体和自旋玻璃

摘要 Z = Al、Ge、Mn、Fe 和 Co 的 Mn100-xZx 铸锭都具有 A13 βMn 结构，直至 x 的某个最大值。纯 βMn 的磁化率从 4 到 400 K ≈ 9 × 10−4，但所有掺杂样品的场冷和零场冷磁化率在低温下增加，并且在自旋冻结温度 Tf 下分叉首先随 x 线性增加。点接触 Andreev 反射显示自旋玻璃样品中存在净自旋极化的证据，但在纯 βMn 自旋液体中则没有。固定矩密度泛函计算表明能量最小值非常浅（
