I wonder is it possible to modify and control in-situ or ex-situ structure, morphology, optical properties etc of thin film from non magnetic material through exposure to magnetic field?
Yes you can check out our paper here in RG on magnetic field treated solutions for cds film growth. Also even your material in non magnetic -i assume you mean "non ferromagnetic" - you can do a search on the magnetic susceptibility of materials (chemistry and physics textbooks, landolt bornstein data base for example) and try to figure out some effects...there are many references for example in calcium carbonate morphology effects upon exposure to magnetic fields..By the way, what kind of materials are you working with? When you mean "magnetic field" what are the magnitudes we are talking about? Uniform, directed fields? Permanent ma gnets?
Sure there are!
However, the possibility of such effects depend on:
1) the film material composition and its electrical proporties;
2) the presence/absence of supporting substrate with electrical/magnetic properties.
So, your question should be more specific.
Here are some examples (WEB sources):

- T. Kimura, et al, Polymer Composites of Carbon Nanotubes Aligned by a Magnetic Field, Advanced Materials, 14, (19), pages 1380–1383, 2002.
- K. Novoselov, et al, Electric Field Effect in Atomically Thin Carbon Films, Science Oct 22, (2004).
Good Luck,

Yes there are , as Kamen said these effects depend on film composition, substrate, structure and also the thermal treatment such as annealing.
A recent study shows magnetic field effect on PL intensity of Sm3+ in GaN thin film. 28% increase in PL intensity under magnetic field of 1000 Oe is reported which could be interesting in potential application of magneto-optical devices. For reference, see the article published in J Mater Sci: Mater Electron (2014) 25:2974–2978. Doi 10.1007/s10854-014-1969-0.
Thank you all for the fruitful answer.
At Abu Zayed Mohammad Saliqur Rahman - could you pleas send me a copy of the cited paper
