Magnetic fields and fluctuations in weakly Mn doped ZnGeP2

We report on our measurements of local and bulk magnetic features in weakly Mn doped ZnGeP2. Utilizing muon spin rotation and relaxation measurements, we identify local ferromagnetic order and fluctuations in the local fields as sampled by an implanted muon (μ+). We also report on field induced ferr...

Description
Summary:We report on our measurements of local and bulk magnetic features in weakly Mn doped ZnGeP2. Utilizing muon spin rotation and relaxation measurements, we identify local ferromagnetic order and fluctuations in the local fields as sampled by an implanted muon (μ+). We also report on field induced ferromagnetism occurring above the claimed paramagnetic to ferromagnetic transition temperature (Tc = 312 K).
