论文摘要
我们研究了$ _ {1-x} $ pr $ _ {x} $ alge的固体解决方案的宏观和微观物理特性。从Cealge进行的系列曲调及其多 - $ \ vec {k} $结构和AB平面的主要时刻，到具有易于c轴铁磁基态的pralge，并与低密度的纳米级纹理磁性域壁壁一起共存。使用AC-，DC-Susceptiblity，电阻率，比热，MUON自旋松弛/旋转和中子散射，我们分析了该系列的磁接地状态。我们提供了进一步的证据，以支持我们先前对纯粹pral中的旋转玻璃的主张。通过介绍PR封闭PR，稳定拓扑多磁场所需的有限磁场被抑制了$ x = 0 $的磁场{k} $磁相。两个末端成员之间的交叉状态发生在$ x = 0.3 $附近，在该地区我们进一步预期野外诱导的拓扑磁相（$ x <0.3 $），以成为零场地状态。
We investigate the macroscopic and microscopic physical properties of the solid solution of Ce$_{1-x}$Pr$_{x}$AlGe. The series tunes from CeAlGe with its multi-$\vec{k}$ structure and a major Moment in the ab-plane, to PrAlGe with an easy-c-axis ferromagnetic ground state co-existing with a low density of nanoscale textured magnetic Domain walls. Using AC-, DC-susceptiblity, resistivity, specific heat, muon spin relaxation/rotation and neutron scattering we analyze the magnetic ground state of the series. We provide further evidence supporting our previous claim for spin-glass like properties in pure PrAlGe. With introduction of Pr to CeAlGe the finite magnetic field required to stabilize the topological multi-$\vec{k}$ magnetic phase for $x=0$ becomes suppressed. The crossover between the two end-member ground states occurs in the vicinity of $x=0.3$, a region where we further anticipate the field-induced topological magnetic phase for $x < 0.3$ to become the zero field ground state.
