Magnetic Field Induced Fermi Liquid Behavior In Mn_(0.95)Cr_(0.05)Si

摘要

Skyrmionic MnSi is expected to be a future spintronic material with an evolution of exotic ground states upon perturbations. Mn_(0.95)Cr_(0.05)Si with a possible Non-Fermi Liquid behavior has been investigated by resistivity measurements performed from 300K down to 2K under external magnetic fields up to 13T. Non-Fermi Liquid behavior with resistivity pa aT~n (n<2), seen at lower fields eventually transformed to the Fermi Liquid behavior for fields of the order of 13T. Such a behavior in this case can be attributed to the nearness of the system to a possible Quantum Critical Point induced by Cr substitution in MnSi.
