Low-field microwave absorption in the superconducting copper oxides

Non Resonant Microwave Absorption (NRMA) Anomalies in High Temperature Superconductors (HTS) Relevance of Electromagnetic Interactions (EMI) and Energy Stabilized Josephson (ESJ) Fluxons

“…This provides information on extremely small temperature and magnetic field dependent microwave absorption (P) changes. (Blazey et al, 1987;Moorjani et al1987;Glarum et al1988) organic superconductors (Haddon et al, 1991) conventional superconductors 14,17 ( Suss et al, 1989;Moorjani et al, 1987)etc. It is evident that markedly different variations in the NRMA signal amplitude in all these superconductors are seen on increasing temperature i.e.…”

“…This was followed by reports on other cuprate based HTS (Portis et al,1987, Dulcic et al1987Pakulis & G.V.Chandershekar,1989;Sugawara et al, 2000;Hashmizume et al2001;Padam et al,1999) and also on a different variety of superconductors like: borocarbides (Kadam et al,1994), oxyflorides (Kadam et al,1995) alkali fullerides (Roberts,1998-II), granular conventional low-T c typeI [Pb, Al, Sn, In etc. ] (Kheifetsand et al, 1990;Blazey et al1988Blazey et al ,1989Suss et al,1989;Kataev et al,1991;Baranowsky et al1991;Moorjani et al1990;Bele et al1994;Blazey et al 1987;Veinger et al 1995),MgB 2 (S.Sarangi & S.V. Bhat, Joshi et al,2002) including newly discovered iron pniticide (Panarina et al 2010;Pascher et al2010 etc.…”

“…In the superconducting state the magnetic field dependent nonlinear absorption [24][25] was observed (Fig. 2.).…”

Detection of Magnetic Transitions by Means of Ferromagnetic Resonance and Microwave Absorption Techniques

“…In our EMR measurements, we also detected a second absorption mode around zero field in amorphous alloys (Montiel et al, 2005) and ferrites (Montiel et al, 2004;Alvarez et al, 2010); however, a detailed discussion on this absorption type is gathered to continuation. The non-resonant microwave absorption (NRMA) was used in 1987 to detect the transition between the normal state and superconducting state in high-Tc superconductor ceramics (Bhat et al, 1987;Blazey et al, 1987;Bohandy et al, 1987;Khachaturyan et al, 1987;Moorjani et al, 1987). This was followed by a large number of reports on not only high-Tc superconductor ceramics (Kim et al, 1993;Topacli, 1996Topacli, , 1998Velter-Stefanescu et al, 1998Padam et al, 1999Padam et al, , 2010Shaltiel et al, 2001;Alvarez & Zamorano, 2004), but also including organic superconductors (Zakhidov et al 1991;Bele et al, 1994;Hirotake et al, 1997;Niebling et al, 1998;Stankowski et al, 2004), the conventional superconductors of type-I and type-II (Kheifets et al, 1990;Bhide et al, 2001;Owens et al, 2001;Andrzejewski et al, 2004) and the newly discovered iron pniticide (Panarina et al, 2010;Pascher et al, 2010).…”
