Volatile organic compounds (VOCs) of lemongrass, garlic, guava and lemon
The volatile organic compounds (VOCs) in the test plants were analysed using coupled gas chromatography/mass spectrometry (GC/MS) on an Agilent Technologies 7890A GC linked to a... -
Spin waves in lightly doped LiGa1-xInxCr4O8
Magnetic frustration - the inability to mutually satisfy all magnetic interactions in a system - is the source of many interesting phenomena, including spin liquids and ices. In... -
Low energy spin wave of BiFeO3 single crystal
Of all multiferroic materials, BiFeO3 stands out particularly with its both magnetic and ferroelectric transition temperatures above room temperatures, more interestingly having... -
Search for incommensurate spin excitation in BaFe1.904Ni0.096As2
Motivated by the observation of incommensure magnetic order in Ba(Fe1-xCox)2As2, we have recently grown BaFe2-xNixAs2 crystals with systematic electron doping level especially... -
Magnetic and lattice excitations in multiferroic BiMn2O5
The exchange-striction mechanism, where parallel or antiparallel alignment of an ion's spin with its neighbour leads to displacements away from or towards the neighbour which... -
Spin dynamics in the extended Kagome system YBaCo4O(7+x)
A recently discovered new class of geometrically frustrated magnets is the family of cobalt oxides RBaCo4O7 (R=rare earth or Y). The structure is built up CoO4 tetrahedra which... -
