Ushbu tezisda marganes nanoklasterlari bilan modifikatsiyalangan p-tipli kremniy asosidagi ko‘p funksiyali datchikning xona haroratida namoyon bo‘ladigan anomal manfiy magnit qarshiligi (MMQ) hamda infraqizil sohadagi fotojavobi tahlil qilinadi. Magistrlik tadqiqoti natijalariga ko‘ra, MMQ qiymati nanoklastersiz kremniyga nisbatan 250–300 marta katta bo‘lib, maksimal qiymati 500 % ga yetadi, magnit maydonga sezgirlik esa 95–107 %/T ni tashkil etadi. Fotoelektrik o‘lchovlarda hν = 0,2 eV energiyadan boshlab fototok bir zumda 2–3 tartibga sakrab o‘sib, anomal qoldiq fotoo‘tkazuvchanlik namoyon bo‘ladi — bu hodisa nanoklastersiz namunalarda kuzatilmaydi. Natijalar Mn nanoklasterli kremniyni bir vaqtning o‘zida magnit maydon va infraqizil nurlanishni qayd etuvchi ko‘p funksiyali yarimo‘tkazgich datchik sifatida qo‘llash imkoniyatini ko‘rsatadi.
