Modern society is faced with an important challenge–how to ensure enough energy and
resources for industrial and population growth and preserve the environment at the same …

We review recent experimental work falling under the broad classification of colossal
magnetoresistance (CMR), which is magnetoresistance associated with a ferromagnetic-to …

Colossal magnetoresistance—a huge decrease in resistance in response to a magnetic field—
has recently been observed in manganese oxides with perovskite structure. This effect is …

Mixed-valence manganese oxides (R1-χAχ) MnO3 (R= rare-earth cation, A= alkali or
alkaline earth cation), with a structure similar to that of perovskite CaTiO3, exhibit a rich …

Half-metallic materials are characterized by the coexistence of metallic behaviour for one
electron spin and insulating behaviour for the other. Thus, the electronic density of states is …

The manganese oxides of general formula RE 1− x M x MnO 3 (RE= rare earth, M= Ca, Sr,
Ba, Pb) have remarkable interrelated structural, magnetic and transport properties induced …

Oxides have become a key ingredient for new concepts of electronic devices. To a large
extent, this is due to the profusion of new physics and novel functionalities arising from …

The features and mechanism of Colossal Magnetoresistance, or CMR, in manganese oxides
as well as device physics are highlighted in this book, with a focus on tunneling MR for some …

The phenomenon of electron tunnelling has been known since the advent of quantum
mechanics, but continues to enrich our understanding of many fields of physics, as well as …

Perovskite manganites exhibit a broad range of structural, electronic, and magnetic
properties, which are widely investigated since the discovery of the colossal …
