摘要

We present measurements of the magnetoresistivity rho xx of URu2Si2 single crystals in high magnetic fields up to 60 T and at temperatures from 1.4 K to 40 K. Different orientations of the magnetic field have been investigated permitting to follow the dependence on 0 of all magnetic phase transitions and crossovers, where theta is the angle between the magnetic field and the easy-axis c. We find out that all magnetic transitions and crossovers follow a simple 1/cos theta-law, indicating that they are controlled by the projection of the field on the c-axis.
