Abstract
Abstract—Magnetic properties of the microcrystalline Sm1 – xZrxFe11Ti (x = 0, 0.1, 0.2) alloys with ThMn12-type structure were investigated. Irreversible jumps of magnetization on major hysteresis loops at low temperatures (2–4 K) were found. The jumps are random either in the magnitude of the magnetic field in which they occur or in their amplitude, and are independent of the chemical composition. There is a specific annealing temperature for each alloy, above which magnetization jumps are not observed in annealed alloys at low temperatures. The magnetic viscosity of Sm0.9Zr0.1Fe11Ti alloy annealed at 700°C was investigated at temperatures of 2–4 K. The magnetic viscosity coefficient has a discontinuity in the field of magnetization jump. This behavior is explained by thermal processes occurring during magnetization of the alloy through the magnetization jump.
