Holmium Metal Introduction

Holmium metal is a soft, malleable, ductile, silvery rare earth metal belonging to the periodic table's lanthanide group. It has the highest magnetic permeability of any element, similar to dysprosium. It is relatively corrosion-resistant and stable in dry air at standard temperature and pressure, but it is easily oxidized in moist air. Holmium has the highest magnetic moment of the naturally occurring elements and forms highly magnetic compounds when alloyed with yttrium. At ambient conditions, Holmium is paramagnetic.
