Abstract
X-ray magnetic circular dichroism measurements were performed on TbNi2B2C i n order to confirm the weak ferromagnetism reported for this material at lo w temperatures. Below approximately 8 K, an increase in the dichroic signal was observed at the Tb L-III edge, consistent with the onset of weak ferro magnetism involving the Tb ions. At an external magnetic field of 500 G, th e ferromagnetic order parameter was obtained, and is in good agreement with the bulk magnetization data measured by a SQUID magnetometer.
