A local approach of magnetism in icosahedral Al–Pd–Mn quasicrystals through nuclear magnetic resonance studies

Magnetism in icosahedral Al–Pd–Mn phases was investigated on a local scale through 27Al and 55Mn nuclear magnetic resonance experiments on polycrystalline ribbons of various compositions. In all samples, a 55Mn resonance line is detected, which reveals the existence of non-magnetic Mn atoms. The pre...

Description
Summary:Magnetism in icosahedral Al–Pd–Mn phases was investigated on a local scale through 27Al and 55Mn nuclear magnetic resonance experiments on polycrystalline ribbons of various compositions. In all samples, a 55Mn resonance line is detected, which reveals the existence of non-magnetic Mn atoms. The presence of magnetic Mn atoms is detected through their influence on the width of the 27Al resonance central line, which increases continuously from 300 to 5 K. Therefore, Al–Pd–Mn icosahedral phases are characterized by a coexistence of magnetic and non-magnetic Mn atoms.
