About the pressure-induced superconducting state of europium metal at low temperatures
In Physical Review Letters 102 (2009) 197002, it was reported that the element Eu becomes superconducting in the pressure and temperature range [84–142 GPa], [1.8–2.75 K]. The claim was largely based on ac susceptibility measurements. Here I point out that recently reported ac susceptibility measure...

520 | |a In Physical Review Letters 102 (2009) 197002, it was reported that the element Eu becomes superconducting in the pressure and temperature range [84–142 GPa], [1.8–2.75 K]. The claim was largely based on ac susceptibility measurements. Here I point out that recently reported ac susceptibility measurements on a hydride compound under pressure that appears to become superconducting near room temperature (Nature 586 (2020) 373) cast serious doubt on the validity of the results for Eu as well as for the hydride. It is argued that the experiments on Eu have to be repeated to either validate or rule out the claim that it is a superconducting element. | ||

The claim was largely based on ac susceptibility measurements. Here I point out that recently reported ac susceptibility measurements on a hydride compound under pressure that appears to become superconducting near room temperature (Nature 586 (2020) 373) cast serious doubt on the validity of the results for Eu as well as for the hydride. It is argued that the experiments on Eu have to be repeated to either validate or rule out the claim that it is a superconducting element.

About the pressure-induced superconducting state of europium metal at low temperatures |
abstract |
In Physical Review Letters 102 (2009) 197002, it was reported that the element Eu becomes superconducting in the pressure and temperature range [84–142 GPa], [1.8–2.75 K]. The claim was largely based on ac susceptibility measurements. Here I point out that recently reported ac susceptibility measurements on a hydride compound under pressure that appears to become superconducting near room temperature (Nature 586 (2020) 373) cast serious doubt on the validity of the results for Eu as well as for the hydride. It is argued that the experiments on Eu have to be repeated to either validate or rule out the claim that it is a superconducting element. |
