Revisiting apparent ideal diamagnetism at ambient conditions in graphene-n-heptane-permalloy systems
Rajendra Dulal, Serafim Teknowijoyo, Sara Chahid +2
We previously reported apparent ideal diamagnetism at ambient conditions in a graphene-n-heptane-permalloy system. At the same time, the experiments revealed inconsistent behavior,…
Glassy magnetic freezing of interacting clusters in LK-99-family materials
Serafim Teknowijoyo, Domenico Napoletani, Vahan Nikoghosyan +1
We report reproducible magnetization anomalies appearing below room temperature in copper-doped apatite materials belonging to the LK-99 family synthesized via hydrothermal methods…
Diode Effect May Assist Finding Proper Superconductivity Mechanism in Copper Oxides
Armen Gulian, Serafim Teknowijoyo, Vahan Nikoghosyan
We present measurements demonstrating that copper-oxide high-temperature superconductors can exhibit broken time-reversal symmetry in the absence of external magnetic fields. Using…
Demonstration of high-impedance superconducting NbRe Dayem bridges
S. Battisti, J. Koch, A. Paghi +10
Here we demonstrate superconducting Dayem-bridge weak-links made of different stoichiometric compositions of NbRe. Our devices possess a relatively high critical temperature, norma…
