Non-resonant microwave absorption (NRMA) in superconducting materials has become a new experimental technique to probe and understand superconducting materials [1]. For example cuprate superconductors are well studied with this technique [2]. At the same time the technique is also evolving. This technique (NRMA) has been used to study magnetic shielding effects/boundary current in Ba_0.34K_0.64Fe₂As₂ single crystals of iron pnictides superconducting sample measured at 9.4 GHz below TC (4.2K-36K). It has been established that a small modulation field used in NRMA experiment yield the boundary current response.
