Surface morphology of PrBa2Cu3O7-ë single crystals after the long lasting high temperature reduction. .
PublicationZaprezentowano wyniki szczegółowej analizy powierzchni kryształów poddanych długotrwałej redukcji wysokotemperaturowej. Badania za pomocą skaningowej mikroskopii (SEM) wykazały obecność niestabilnych strukturalnie krystalitów powstałych w wyniku rozpadu powierzchni kryształów. Zanikanie zaindukowanego przy pomocy obróbki wysokotemperaturowej nadprzewodnictwa może być spowodowane migracją defektów podsieci Pr-Ba z wnętrza...
