Thermal memory effect in Mn(CoFe)Ge intermetallic compound

The temperature memory effect (TME) in MnCo0.97Fe0.03Ge shape memory alloy, fabricated as pellets via arc-melting, has been investigated once the martensite phase was stabilized at room temperature. The results revealed that TME appears during the reverse transformation of thermally induced martensi...
