Abstract

The electronic structure of the Zr-based metallic glasses has been investigated by theoretical and experimental approaches. One approach is band calculations of the Zr2Ni (Zr66.7Ni33.3) compound to investigate the electronic structure of the Zr66.7Ni33.3 metallic glass (ΔTx = 0 K) of which the local atomic structure is similar to that of the Zr2Ni compound. The other is photoemission spectroscopy of the Zr50Cu35Al15 bulk metallic glass (BMG) (ΔTx = 69 K). Here ΔTx = Tx - Tg where Tx and Tg are crystallization and glass transition temperature, respectively. Both results and previous ones on the Zr55Cu30Ni5Al10 BMG indicate that there is a pseudogap at the Fermi level in the electronic structure of these Zr-based metallic glasses, independent of the value of the ΔTx. This implies that the pseudogap at the Fermi level is one of the factors that stabilize the glass phase of Zr-based metallic glasses.
