Magnetic properties of spinel CuCrZrS4 under pressure

► We study magnetic properties of spinel CuCrZrS4 under pressure up to 8 GPa. ► Spin-glass freezing temperature at ambient pressure obeys the theoretical AT line. ► Spin-glass freezing temperature increases monotonically with increasing pressure. ► The magnitude of ac-magnetic susceptibility is reduced by the pressurization. ► By pressurization, the strength of magnetic frustration is enhanced.
