Popis: B basedrare-earth hard magnetic materials are known because of their high coercivity andlarge energy product. The newer nanocrystalline magnetic materials based onNd{Fe{B alloys prepared by the rapid quenching of the liquid, known as exchange-coupled nanocrystalline composite hard magnetic materials, are almost of the samequality despite reduced amount of expensive rare-earth Nd [1{3]. On the otherhand, there are also experiments trying to enhance the qualities of the stoichio-metric material adding even more neodymium atoms to the basic structure.2. Results and discussionThree kinds of commercial materials being of the above-mentioned com-positions (see Table I for constitution) were compared using room temperatureM˜ossbauer spectroscopy of
