“…чи-стых и допированных немагнитными элементами окис-лов HfO 2 [1][2][3], TiO 2 [4,5], ZrO 2 [6][7][8][9][10], ZnO [11][12][13], SiO 2 [14][15][16] привлекают большое внимание из-за их потенциального применения в устройствах спинтроники. Авторы [17,18] сообщали об обнаружении ферромагне-тизма при комнатной температуре (ФМКТ) в наноча-стицах отдельных оксидов, в частности оксида Al 2 O 3 .…”

“…34,38 On the other hand, Kopnov et al report on an interface magnetism occurring at the Si/SiO 2 interface. 40 Within this study they claim that the dependence of the magnetic response is correlated to surface pre-treatment using KOH etch solution. 40,41 Basically, all the above described possibilities have the ability to produce a magnetic signal which lies in the observed range of 1 Â 10 À4 -1 Â 10 À5 emu.…”

“…40 Within this study they claim that the dependence of the magnetic response is correlated to surface pre-treatment using KOH etch solution. 40,41 Basically, all the above described possibilities have the ability to produce a magnetic signal which lies in the observed range of 1 Â 10 À4 -1 Â 10 À5 emu. Therefore, besides the proper sample handling, it is most essential to remove the native oxide and to strip off any possible contamination when working within such low magnetic regimes to avoid any misinterpretation of the measurements results.…”

“…The instances include oxide thin films [1] and nanoparticles, [2] either undoped or doped with only a few percent of magnetic 3d ions, gold nanoparticles, [3] organic layers on gold surfaces, [4] graphite and related materials, [5,6] and, most recently, etched silicon. [7] Features of the ferromagnetic signal are that it shows little hysteresis, with a coercivity of less than 10 mT. There is often little or no temperature dependence of the magnetization curve in the range 4-400 K, and sometimes the signal is highly anisotopic with respect to the substrate surface.…”

“…Recently Kopnov et al [7] reported that it was possble to obtain a large magnetic signal by etching a silicon wafer in KOH. This was a straightforward procedure, which promised to allow at least one instance of phantom ferromagnetism to be systematically examined.…”
