Magnetic and superconducting phase diagrams of single crystal HoNi2B2C

In plane measurements of resistivity and magnetic properties are reported for HoNi2B2C. The superconducting transition as well as several magnetic phase transitions are observed with measurements of R(T,H), M(T,H), and (T,H). Three magnetic transitions occur below the superconducting transition temperature of 8 K. Two of these are field dependent while the other is relatively field independent. Phase diagrams constructed from the different measuring techniques will be discussed for the in-plane, <100> and <110>, directions of the magnetic field and the out-of-plane, <001>, direction.
