Using a high-pressure cell specially designed for a Magnetic Property Measurement System, magnetic hysteresis measurements were conducted under high pressures of up to 1 GPa on natural plagioclase crystals containing much acicular SD magnetite. Coercivity and saturation magnetization were nearly constant with pressure, while saturation remanent magnetization and coercivity of remanence decreased with pressure at moderate rates of -8 per cent GPa-1 and -18 per cent GPa-1, respectively. These results suggest that temperature effects govern the magnetic behaviour of acicular SD magnetite grains in the middle and lower crusts. © The Authors 2015., 金沢大学理工研究域地球社会基盤学系}, pages = {394--401}, title = {Pressure effect on magnetic hysteresis parameters of single-domain magnetite contained in natural plagioclase crystal}, volume = {202}, year = {2015} }
