· Co2 Ge2 Ho1

Co₂Ge₂Ho₁ is an experimental intermetallic compound combining cobalt, germanium, and holmium—a rare-earth transition metal combination that belongs to the broader family of magnetic semiconductors and intermetallics. This material is not widely commercialized and represents research-phase work, likely pursued for its potential magnetic properties (holmium contribution) and semiconductor characteristics (germanium backbone) in applications requiring integrated magnetic and electronic functionality. Interest in this class of materials stems from potential use cases in spintronics, magnetic sensing, and advanced electronics where ferromagnetic semiconductors could enable new device architectures unavailable with conventional semiconductors or permanent magnets alone.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
