He said: "Everyone is putting the effort in and no-one is slacking off.
"We are all in it together as a team. It's a tight-knit group from what I have seen the past couple of days.
"I think we have got the quality as well to turn the results around. Hopefully, it's onwards and upwards, but we will see what happens."
Lowry was one of three loan signings made by under-pressure Argyle manager Paul Sturrock at the end of last week.
Manchester United defensive duo James Chester and David Gray were also snapped up.
Gray, who had a successful loan spell with Argyle last season, played at right-back against Newcastle.
