For annealing in vacuum at 800 °C, a growing ferromagnetic signal is seen with time while for a similar annealing in air, the magnetism vanishes. The magnetism is concomitant with a surface conductivity which at low temperatures shows tunneling characteristics. Here, we show that Ni magnetic impurity (in TiO 2 crystals at | Source Title: | Applied Physics Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/82980 | ISSN: | 00036951 | DOI: | 10.1063/1.4756799 |
