Abstract :
Nd13.5Fe80Ga0.5B6 R-rich alloy and two types of NdxFe93-xNb1B6 R-lean alloys are used to prepare compacted and die-upset magnets. The microstructure of the samples are examined using a high resolution scanning electron microscope. The cubic shape specimens are magnetized in a superconducting quantum interference device (SQUID) and the room temperature demagnetization curves are measured using a SQUID and a vibrating sample magnetometer (VSM). All measured demagnetization curves are corrected for the self-demagnetizing field using a demagnetizing factor.
